研究了液固扩散偶法制备Mg-9Al/Ti冶金连接的显微组织和力学性能。结果表明，Mg-9Al/Ti界面形成了冶金结合，随着热处理时间的延长，界面处的Mg 17 Al 12相长大。采用顶出试验研究了Mg-9Al/Ti冶金连接的剪切强度。结果表明，随着热处理时间的延长，剪切强度呈增加趋势。结果表明，断裂是在界面处沿沿着Mg-9Al基体发生的。Mg-9Al/Ti冶金连接的界面反应主要是Al和Ti元素的扩散。通过能谱分析（EDS）、X射线衍射分析（XRD）和热力学分析，发现Mg-9Al/Ti冶金连接界面上只有Al 3 Ti金属间化合物。这些结果清楚地表明，在界面处形成的Al 3 Ti的化学相互作用改善了Mg-9Al/Ti冶金连接的机械性能。
Microstructures and mechanical properties of Mg-9Al/Ti metallurgical bonding prepared by liquid-solid diffusion couples were investigated. The results indicate that a metallurgical bonding was formed at the interface Mg-9Al/Ti, and the Mg17Al12 phase growth coarsening at the interfaces with the increase in heat treatment time. Push-out testing was used to investigate the shear strength of the Mg-9Al/Ti metallurgical bonding. It is shown that the shear strength presents an increasing tendency with the increased heat treatment time. The sequence is characterized, and the results show that the fracture takes place along the Mg-9Al matrix at the interface. The diffusion of Al and Ti elements play a dominant role in the interface reaction of Mg-9Al/Ti metallurgical bonding. By energy-dispersive spectroscopy (EDS), X-ray diffraction (XRD) and thermodynamic analysis, it was found that Al3Ti is the only intermetallic compound at the interface of Mg-9Al/Ti metallurgical bonding. These results clearly show that chemical interaction at the interface formation of Al3Ti improves the mechanical properties of Mg-9Al/Ti metallurgical bonding.
